- Plate Width: 1 inch for precision/curls; 1.5+ inches for speed on long hair.
- Hair Type Match: Fine—lower heat/single-pass like CHI; Thick—wide plates/high heat like T3 or BaByliss.
- Pro Advice: Limit to 1–2 passes max; section hair; use on dry hair unless it’s a wet-to-dry model. For longevity, look for 1–2 year warranties.
- Reddit Consensus: Users emphasize GHD/CHI for reliability, Dyson for “healthiest” results, and BaByliss for curls—avoid cheap coated plates to prevent snagging.
